      [es6] Fix parsing of 'yield' in function and generator expressions · 2ea7f3c8
      adamk authored 
      In a function expression, 'yield' is allowed, even if the expression
occurs inside a generator. Similarly, even in a non-generator,
a generator expression's name must not be 'yield'.

      PPC: [builtins] Sanitize the machinery around Construct calls. · fe14ba45
      mbrandy authored 
      Port 374b6ea2

Original commit message:
    There's no point in collecting feedback for super constructor calls,
    because in all (interesting) cases we can gather (better) feedback from
    other sources (i.e. via inlining or via using a LOAD_IC to get to the
    [[Prototype]] of the target).  So CallConstructStub is now only used
    for new Foo(...args) sites where we want to collect feedback in the
    baseline compiler.  The optimizing compilers, Reflect.construct and
    super constructor calls use the Construct builtin directly, which allows
    us to remove some weird code from the CallConstructStub (and opens the
    possibility for more code sharing with the CallICStub, maybe even going
    for a ConstructICStub).

    Also remove the 100% redundant HCallNew instruction, which is just a
    wrapper for the Construct builtin anyway (indirectly via the
    CallConstructStub).

    Drive-by-fix: Drop unused has_function_cache bit on Code objects.

      PPC: [stubs] Change CallICStub to utilize the ConvertReceiverMode. · ee72c407
      mbrandy authored 
      Port d80fd48e

Original commit message:
    The CallICStub has call-site specific knowledge about the receiver,
    which we did not utilize; plus the CallICStub does in some case know
    whether it is about to [[Call]] a function or potentially some other
    callable. In the common case we actually know that the target is a
    function and so we can use the CallFunction builtin directly instead
    of redispatching in the Call builtin.

      PPC: Make arguments adaptor not clobber new.target. · 395884de
      mbrandy authored 
      Port c1e7c8d9

Original commit message:
    This ensures that the ArgumentsAdaptorTrampoline does not clobber the
    new.target value, but rather passes it through to the callee unaltered.
    Note that callees do not yet use the new.target value so far.

    This is a preparatory CL to allows us passing new.target in a register
    instead of via a side-channel through the construct stub frame.

      PPC: [turbofan]: Implement tail calls with more callee than caller parameters · 1d1557d8
      mbrandy authored 
      Port c6d310da

Original commit message:
    * Adds a PrepareForTailCall instruction that bumps the stack in the case that
      the number of parameters passed to the callee causes the stack to exceed the
      calleer's frame size.
    * Uses the gap resolver to move the saved caller return address and frame
      pointer to the approprate location in the tail-called frame.

      PPC: Fix object initialization when slack tracking for it's map is still enabled. · 07b50849
      mbrandy authored 
      Port 2fc2cb99

Original commit message:
    The old code was not ready for properly initialize objects with non
    standard headers and non zero in-object properties number.

    MacroAssembler::Allocate() implementations now return both start and
    end addresses of the new object (done by parameter renaming).
